[gdal-dev] RE Python ogr GetFieldAsString problem

[Steve.Toutant at inspq.qc.ca]

I agree, no patch. 
Actually the patch will be on my side. I might use python re, to replace 
the comma by dot int he WFS response, for numeric field

If others are in the same situation, your suggestions are welcome
thanks

To be pedantic, GetFieldAsString() does not truncate the value. The value 
is
truncated before, in the GML reader, when inserting the value from the GML 
as a
real value into the OGR real field.

> Is it because it also use a  GML reader?

The conversion from the XML content to the real value is done with a 
function
(CPLAtof()) that assumes dot as the decimal character, which is the 
correct
behaviour in that instance.

I guess you would have issues with most GML readers, that's why I'm a bit
hesitant into committing the patch.
